MRB24H-BB

Rotary Switches

Rotary switches are switching elements often used in industrial automation and control applications. Rotary switches are controlled by turning a handle or lever, and often feature multiple positions that can be used to activate different circuits or components. Examples of these switches include the Reversing Switch and the Pushbutton Reversing Switch.

One type of rotary switch is the MRB24H-BB. This switch, designed for high current load applications, consists of a 24-position rotary handle and a durable die-cast base. The switch is designed for high-load applications, with a maximum power rating of 60HP at 600VAC.

Application Field

The MRB24H-BB rotary switch is primarily used in industrial automation and control applications, due to its versatile design and durable construction. The switch can be used to control a wide variety of applications, including lighting, heating, process control, and relays. The switch can also be used for generator operations and motor control.

The switch is designed for a wide range of operating conditions, and can be used in environments with extreme temperatures and hazardous atmospheres. The switch is UL listed for all installations requiring a UL 508A rating.

Working Principle

The working principle behind the MRB24H-BB switch is quite simple. The switch features a rotating handle, which is used to control the electrical connections. When the handle is turned, the switch contacts make or break the electrical connections. This is known as “make before break” operation.

The switch is also designed to have a “retentive action”, meaning that when the switch is turned, the contacts will remain in the last position until the handle is manually reset. This feature is useful for controlling applications that require the contacts to remain in the same position for an extended period of time.

The MRB24H-BB switch is designed to be highly reliable and durable, and can withstand hundreds of thousands of operating cycles. The switch is also designed to be easy to install and maintain, and requires minimal wiring for operation.

Conclusion

The MRB24H-BB rotary switch is a versatile, reliable, and cost-effective switching element that is ideal for use in industrial automation and control applications. The switch features 24 positions, a “make before break” operation, and a “retentive action” feature, making it an ideal choice for high-load applications. The switch is also easy to install and maintain, and can withstand hundreds of thousands of operating cycles.
